Zusammenfassung:	A pneumatic tire comprising a carcass (220), the carcass (220) having one or more cord reinforced plies (240, 260) and a pair of bead portions (180) each comprising a bead core (200) is disclosed. At least one of the bead portions (180) comprises a chafer (400) formed of at least two zones (410, 420, 430). The two zones (410, 420, 430) are formed of a different material. The first zone (410) extends from axially inward of the bead core (200) to an end (411) axially outward of the bead core (200). The second zone (420) extends from the end (411) of the first zone (410) to an end (422) of the second zone (420) located radially outward of the end (411) of the first zone (410).
